目的 探讨增强T2FAIR系列在结核性脑膜炎(TBM)中的诊断价值。方法 选择临床疑似TBM并初次行MR检查的患者80例,根据TBM诊断评分标准和颅内结核影像学分型专家共识作为临床确诊依据。最终56例经临床确诊为TBM(脑脊液结核杆菌抗酸检测阳性)。行常规系列颅脑扫描后增加增强T2FIR系列扫描。由三位经验丰富从事影像专业诊断不同级别的医师分别进行独立分析诊断,以明显强化、轻度强化和无明显强化对比分析增强三维快速扰相梯度回波T1WI(T1GRE3D-FS)序列和增强T2FIR系列对TBM脑膜病变和脑实质的显示程度。结果 增强T2FLAIR系列52例显示脑膜明显强化占92.5%;4例不明显强化占7.5%。T1GRE3D-FS序列 8例明显强化占14%,39例轻度强化占70%;9例无明显强化占16%。增强T2FLAIR系列43例显示脑实质明显强化占76.8%;13例轻度强化占23.2%。T1GRE3D-FS序列48例明显强化占86%;8例轻度强化占14%。两系列对脑实质的显示均有轻度强化。结论 增强T2FAIR系列可作为TBM早期常规系列用于TBM的MR增强检查,能显著提高TBM影像诊断的准确性,,弥补了常规MR增强TlWI对结核性脑膜炎诊断的不足。

Objective To investigate the diagnostic value of enhanced T2FAIR series in tuberculous meningitis (TBM) patients. Methods 80 patients with suspected clinical TBM and initial MR examination were selected as the basis for clinical diagnosis according to the TBM diagnostic scoring standard and the expert consensus of intracranial tuberculosis imaging classification. Finally,56 cases were clinically confirmed as positive for acid resistance in TBM. Enhanced T2FIR series scans were added after routine series craniocerebral scanning. Independent diagnostic analysis was performed by three experienced imaging specialists. By different levels of diagnosis with significant enhancement, mild enhancement and no mild enhancement, we made contrast analysis in display of enhanced three-dimensional fast scrambling phase gradient echo T1WI (T1GRE3D-FS) sequence and enhanced T2FIR series on TBM meningeal lesions and brain parenchyma. Results 52 cases of enhanced T2FLAIR series showed significant enhancement of the meninges in 92.5%; in 4 cases,7.5% were not significantly enhanced. 8 cases of T1GRE3D-FS sequences were significantly enhanced, accounting for 14%, 39 cases of mild enhancement accounted for 70%; no significant enhancement was found in 9 cases, accounting for 16%. Enhanced T2FLAIR series of 43 cases showed significant enhancement of brain parenchyma accounted for 76.8%; 13 cases of mild enhancement accounted for 23.2%. 48 cases of T1GRE3D-FS sequences were significantly enhanced accounted for 86%; 8 cases of mild enhancement accounted for 14%. Both series showed mild enhancement of brain parenchyma. Conclusion The enhanced T2FAIR series can be used as TBM early routine series for MR enhanced examination, it may significantly improve the accuracy of TBM imaging diagnosis, to make up the deficiency of conventional MR.

Objective To investigate the clinical characteristics and related high risk factors of secondary pulmonary tuberculosis complicated with pulmonary fungal infection. Methods Data of patients with secondary tuberculosis admitted to Guangzhou Chest Hospital from July 2017 to October 2019 were collected. All patients with a course of disease longer than 3 months were divided into the fungal infection group (n =106) and the non-fungal infection group (n =100) for retrospective analysis. Results Univariate analysis results showed that there were statistical differences in combined other pulmonary diseases, non-initial treatment, hemoptysis, cavity, application of broad-spectrum antibiotic > for 1 week, and invasive operation (P<0.05). Logistic multivariate analysis showed that >1 week of broad-spectrum antibiotics and invasive procedures were independent risk factors for fungal infection (P<0.05). Conclusion Patients with tuberculosis who are treated with broad-spectrum antibiotics and invasive procedures should be alert to the risk of fungal infection, early prevention and treatment should be undertaken.

Objective To discuss value of the CT features of atypical pulmonary tuberculosis with pulmonary interstitial changes and improve the early diagnosis of pulmonary tubeculosis. Methods The CT imaging data of 44 patients with atypical pulmonary tuberculosis with interstitial changes was collected from January 2018 to December 2018,and the imaging characteristics were analyzed. Results In 44 cases of atypical pulmonary tuberculosis,14 cases of atypical pulmonary tubeculosis were the localized distribution,13 cases were mainly in the right upper lobe,and 30 cases were diffuse distribution. The atypical pulmonary tuberculosis of the localized and diffuse distribution mainly with interstitial changes was characterized by tine reticular shadow,micnodule,thickening of bronchiole wall and thickening of interlobular Septa. Tree-bud sign and ground-glass shadow were common in diffuse distribution,and the proportions of cavity,bronchiectasis,mediastinal lymphadenopathy calcification,pleurisy and bullae were higher than that in localized distribution. The atypical pulmonary tuberculosis patients with localized pulmonary interstitial changes (14 cases) have a favourable prognosis,13 cases with significant absorption,1 case with favourable absorption,and 18 cases with the atypical pulmonary tuberculosis patients with diffuse pulmonary interstitial changes (30 cases) with significant absorption,6 cases with no absorption or poor absorption. Conclusion The atypical pulmonary tuberculosis with interstitial changes has its characteristics,and the CT features is helpful to improve the clinical diagnosis and better evaluation of treatment prognosis.

Objective To understand the registration situation and epidemic characteristics of tuberculosis patients in Haizhu district of guangzhou, and to provide a basis for further prevention and treatment of tuberculosis in Haizhu district. Methods The data of tuberculosis patients registered at present address in the TB information management system of Haizhu district from 2008 to 2017 were collected, and the registration data of tuberculosis patients were analyzed using descriptive epidemiological methods and relevant statistical methods. Results From 2008 to 2017, 14 384 cases of tuberculosis patients were reported in Haizhu district. The annual reported incidence rate decreased from 105.3/100,000 in 2008 to 73.1/100,000 in 2017, showing a down ward trend (χ² = 164.973, P<0.001). The relative incidence of male and female was 2:1; all age groups had morbidity, of which 25~34 years old group had the largest number of cases, accounting for 21.61% of the total number of cases; in occupational distribution, household chores and unemployed were the most, accounting for 34.48 %, followed by other (non-fixed occupations), accounting for 17.29%, retired people, accounting for 15.12%, and school students accounting for 5.52%. In terms of regional distribution, the average annual incidence rate of each street varied greatly, with the highest being 131.23/100,000 and the lowest being 66.40/100,000. The difference is statistically significant(χ²=164.973,P<0.001). Conclusion The incidence of tuberculosis in Haizhu district of Guangzhou has been decreasing year by year, but the incidence of tuberculosis in some streets is still more than 100/100,000. Male population, 25~34 years old group and low-income population (domestic and underemployed, irregular occupation, retired population) are the main population for prevention and control. Students have a large number of cases of tuberculosis, so we need to strengthen prevention, control and screening of tuberculosis in schools.
